Which is main ingredient in cement? Lime or calcium oxide is the most important ingredient of cement.Clinker - International Materials,Clinker is the main ingredient used in the manufacture of Portland cement. Clinker is formed in lumps or nodules, usually 3-25mm in diameter, by sintering limestone and alumino-silicate (clay) during the cement kiln stage.
